Handles discrete placements labeling algorithms.
ALcdGXYDiscretePlacementsLabelingAlgorithm
The main class of this package is ALcdGXYDiscretePlacementsLabelingAlgorithm
.
This class provides an abstract implementation of ILcdGXYLabelingAlgorithm. Labeling algorithms
can easily be created using this class by creating a label iterator, a label placement iterator
and a label placement evaluator. This class also has the advantage of being easy to wrap.
Implementations
This package contains a few ALcdGXYDiscretePlacementsLabelingAlgorithm implementations:
TLcdGXYLocationListLabelingAlgorithm
: This labeling algorithm tries a fixed number of custom label locations.TLcdGXYOnPathLabelingAlgorithm
: This labeling algorithm tries to place the labels on a path.TLcdGXYInPathLabelingAlgorithm
: This labeling algorithm tries to place the labels inside a (polygonal) path.TLcdGXYLabelPainterLocationLabelingAlgorithm
: This labeling algorithm tries a number of label locations and bounds that are retrieved from the layer's label painter.TLcdGXYDependantLabelsRemovalWrapper
: This labeling algorithm wrapper defines a dependency which can be used to define if labels are omitted based on the omitting of other labels.

ClassDescriptionThis abstract class implements an abstract algorithm that can be used to compute label placements.This wrapper can be used to create a labeling algorithm wrapper based on the
ALcdGXYDiscretePlacementsLabelingAlgorithm
abstract algorithm.This interface provides methods to return paths that can be used during labeling.This composite labeling algorithm combinesALcdGXYDiscretePlacementsLabelingAlgorithm
s into one labeling algorithm.This labeling algorithm tries to find a valid position for a curved path text label.This wrapper used a dependency relation between labels to add extra behavior to the labeling.Path aware labeling algorithm.This path provider can provide paths for most supported shapes.This labeling algorithm is a greedy algorithm based on the label locations provided by each label'slabel painter
.This labeling is a greedy labeling algorithm that uses free placement (seeILcdGXYLabelPainter2
) to determine label locations.Path aware labeling algorithm.Alignment mode that determines if label are placed on, outside or inside the paths.This labeling algorithm is a greedy labeling algorithm that only tries one placement per label.
